how to use the wedge anchor bolt

The repairing gecko extends into the tube sheet hole, and the end of the tube rolls to expand the inner wall of the tube, causing plastic deformation, increasing the diameter of the tube, and the tube head completely fits on the wall of the tube sheet hole, and forces the tube sheet to produce Elastic deformation. When the tube expander is removed, the elastic deformation of the tube sheet wants to restore its original shape, and the plastic deformation of the tube end cannot be restored. . In addition, the car repair gecko also needs to choose the appropriate embedding depth according to the thickness of the fixed roof. With the increase of the embedding depth, the tension will increase according to the increase of the embedding depth. The car repair gecko also has an expansion effect after being reliable. In order to ensure the quality of the tube expansion, it is necessary to do the work of returning tools, measuring tools and operators before expanding the tube. During the inspection, the protective coating on the wall of the pipe hole should be cleaned first, and the processing quality of the wall of the pipe hole should be checked.
The amount must not have sand holes, dents, edge burrs and vertical scores; the depth of vertical or spiral scores must not be greater than 0.5mm, and the width should not be greater than 1mm, scores
The distance to the edge of the hole shall not be less than 1/3 of the thickness of the hole wall, and shall not be less than 4mm
